“The evidence that has been gathered is all leading to a consistent conclusion that they’ve been murdered,” DA Brad Berry said.

“There is a lot of other evidence and other information that investigators have put together which aid in the conclusion here that we believe that they’ve been killed.”

Wolfe made an initial appearance in Yamhill County court on Tuesday, where he is being held without bail. His next appearance is June 7.

The probable cause documents describe the days after Karissa Fretwell went missing and her relationship with Wolfe, who was her son Billy’s father. They also describe how police watched surveillance footage of Wolfe on the night of May 13, the night the Fretwells allegedly went missing.

The documents also show that Wolfe and Fretwell’s cellphones pinged in the same areas that night. Police interviewed Wolfe on May 18 and 20, where he said he hadn’t seen them since April 15.

Fretwell, 25, and her 3-year-old son were reported missing May 17. Wolfe was arrested at Blue Star Donuts in downtown Portland on May 24.
